VizieR Online Data Catalog: 25 Ori group low-mass stars (Downes+, 2014)
Abstract
Multi-epoch optical V-, R-, I-band and Hα observations across the entire Orion OB1 association (spanning ~180deg2) were obtained as part of the CVSO (Briceno et al., 2005AJ....129..907B, Cat. J/AJ/129/907), being conducted since 1998 with the Jurgen Stock 1.0/1.5 Schmidt-type telescope and the 8000x8000-pixel QUEST-I CCD Mosaic camera, at the National Astronomical Observatory of Venezuela.
During 2009 a new dedicated 4m survey telescope, the Visible and Infrared Survey Telescope for Astronomy (VISTA), located at ESO's Paranal Observatory, was commissioned by the VISTA consortium. For the Galactic Science Verification of VISTA, an ~30deg2 area of the Orion OB1 association, which included the Orion Belt region, part of the Orion A cloud, the 25 Orionis and σ Ori clusters, was imaged in the Z, Y, J, H and Ks filters, during 2009 October 16 to November 2.
